The CEMA Steuersatzlager ACB 46,9 x 34,1 x 7 x 45°/45° is a high-quality headset bearing designed to deliver smooth, precise steering performance on a wide range of bicycles. Built around an angular contact bearing (ACB) design, it is engineered to handle both radial and axial loads, which are common in modern headsets during hard braking, cornering, and rough terrain. The carefully matched 45°/45° contact angles help ensure stable, play-free steering and reliable alignment of fork and frame, contributing to a more confident and predictable ride.
CEMA is known for producing durable, low-friction bearings, and this headset bearing is no exception. It is typically manufactured with high-grade steel races and quality balls, often combined with effective sealing to keep out water and dirt. This makes it a smart replacement choice when refreshing a worn or rough headset, or when upgrading to a smoother, longer-lasting bearing. Whether you ride road, gravel, or mountain bikes, a precise headset bearing like this can noticeably improve steering feel, reduce maintenance needs, and extend the life of your cockpit components.
